Limitations:

Doesn't expose all ZBar functionality, including:

No video functions

No low-level interfaces (scanner, decoder)

Additionally, there is a zbar <= 0.10 issue with JPEG decoding; see lib/zbar/jpeg.rb
for more. You can check your ZBar::JPEG.bugged? status if you're
curious. Otherwise, just try using it, and see if you get a warning on
stderr.

Contributing

Fork the project.

Make your feature addition or bug fix.

Add tests for it. This is important so I don't break it in a future
version unintentionally.

Commit. Don't change VERSION, or if you do, do it in a
separate commit.
